Don't tire of doing little things for others, because sometimes those little things occupy the biggest part of their heart. In life we cannot always do great things, but, as Mother Teresa said, we can always do small things with great love. At the end it is not only about making a living, it is about making a difference
Don't be the person who blames others or makes excuses. One of the most important keys to success is having the discipline to do what you know you should do even when you don't feel like doing it--and those daily decisions often involve taking responsibility for your own choices and actions. Remember that your actions do affect other people, so always be careful with what you say and do.
